Hi,
I am trying to connect my ‘samsung watch 4 classic’ to ‘Watch Face Studio’ by going through my Samung S21. When I click ‘Run on Device’ I see my S21, but then when I click on S21 it comes out Waring’s message. I have enabled all debug settings on both phone and watch, but it doesn’t work. Can anyone help me out? Thanks Andrea.
I have never gotten USB Debugging to work myself. I’ve seen others users in the same situation. I may give it a try later but WiFi debugging is pretty easy. Just be sure that your computer and watch are connected to the same network.
If you really need to use USB debugging due to some firewall let me know and I’ll try. But if it is just you don’t have a Wifi you can buy one for a computer really cheap and use your mobile for a wifi hot spot.

Hello,
thanks for the quick reply, but i also tried debugging wify, but although the clock address is correct and responds to ping, it doesn’t work.
I am attaching some photos.In the attached image ‘settings.jpg’, I show how the configuration should be, but I don’t understand what is ‘Wear companion app’,
I don’t have an app with this name and kind of settings. My watch is the SM-R890NZKAEUE model.
Thanks for the help.
Andrew
I am so sorry that is my mistake, I forgot to tell you there is a bug.
Try to Run on device and click the plus to add the watch IP Address.
The first time it will say no compatible devices around same time you will get an allow Debugging pop up on your watch.
Cancel the search and restart and then run on device again and your watch will pop up.

nothing to do, after entering the ip address of the clock and clicking OK, nothing popup appears on the clock display 
Thanks, Andrea
Hello,
I wanted to inform you, for your knowledge, that I was able to connect to the clock, via ‘Android Debug Bridge’, by installing ‘adb-setup-1.4.3.exe’ on the pc, in this way via Android Studio I was able to create a whatchface and load it! When I connect from the terminal ‘adb connect 192.168.0.100’, the clock asks me for a debug confirmation. Unfortunately it doesn’t work with ‘WatchFaceStudio’.
Thanks again, Andrea
There is no reason to use adb-setup-1.4.3.exe unless you are running Windows 7.
Make sure Developer Options is on and ADB Debugging by WiFi is enabled.
Using File manager copy the address where you installed adb by default
C:\Users\USERNAME\AppData\Local\Programs\WatchFaceStudio\tools\window
(copy the address as text from file manger using right click on the address bar)
Open a command prompt
navigate to the folder address
cd C:\Users\USERNAME\AppData\Local\Programs\WatchFaceStudio\tools\window
Then type
adb connect 192.168.x.x:5555 (where 192.168.x.x is your watch’s IP address).
It may take a minute to connect or give a failure response
If you get a rejected error or something check your watch debugger settings.
Try in developer options to revoked permissions and force new acceptance. do the connect again.
select “run on device” within Watch Face Studio, your watch should show up. But probably won’t restart Watch Face Studio if it doesn’t.
If it connects but will not run on device create a new keystore in a new keystore folder
